THERON DAVIS, OF NEW-YORK, N. Y.

FAUc'e'r.

T 0 all whom it may concern:

Be it known that l, THERON DAVIS, of the city, county, and State of New York, ha e invented a new and useful Improvement in Faucets, of which the following is a full clear, and exact description.

My invention relates to improvements in faucets, and the object of my invention is to produce a self closing faucet which is particularly adapted for use as a water faucet, but can be used for drawing other liquids under pressure.

shown in Fig. 2.

More particularly my invention is intended to provide a faucet which is simple in construction, which avoids the use of springs in its make-up, which has a ball valve adapted to be easily opened to permit water to pass, and which has a closing float actuated by wvater pressure, through which float the water can readily pass, but which serves under moderate pressure to instantly close the valve automatically if the handle of the faucet is freed.

Another object of my invention is to produce a faucet which, as stated, is inexpensive, positive in operation, and constructed so that all the parts are readily accessible and can easily be reached for renewal, repair or cleansing.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar reference characters indicate corresponding parts in all the views.

Figure 1 is a side elevation of the faucet embodying my invention. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a cross section on the line 3 3 of Fig. 1, said section being at right angles to that Fig. 4 is a broken section on the line 4-4 of Fig. 1, and Fig. 5 is a cross section on the line 55 of Fig. 1.

The faucet has a casing 10 which can be made in any approved design and which has preferably a threaded base portion 11 to connect with an ordinary service pipe or coupling as at 12, while at the outlet end of the casing is another screw threaded portion 13 adapted to receive the delivery spout 14, but obviously the arrangement of the intake and outlet parts is subject to any change to meet different requirements. The casing has a bore 15 which is preferably, though not necessarily, vertical, and this discharges into a chamber 16, which for convenience is preferably cylindrical. The chamber 16 should Specification of Letters Patent.

be of uniform cross section preferably throughout, but necessarily between the inlet through the bore 15 and the valve seat 17. At the bottom of the chamber 16 is a valve seat 17, through the bore of which the water or other liquid passes. On this valve is a 'asket 18 to permit the valve to be seated snugly thereon, as presently described, and the gasket is held in place by a narrower washer 19 which is securely attached to a bail 20 which is arranged vertically in the chamber 16, and should extend up into contact with the cap 21 of the chamber, although this is not essential. The cap 21 screws to the wall of the chamber 19, is provided with a boss 22 to enable it to be turned readily, and it preferably abuts with a gasket 23 which is inserted between a shoulder on the cap, and the top edge of the wall of the chamber 16. A ball valve 24 fits upon the gasket 18, and the valve also abuts with a float 25, preferably of metal, which rides on the valve and which should be concaved a little on the under side, as shown in Fig. 3, to fit the valve. The float 25 has openings 26 through which the bail 20 extends, and thus the float is guided on the bail. The float 25 has also numerous holes 27 therethrough for the passage of the Water or other liquid. There are enough of these holes to permit the water to flow without apparent hindrance through the faucet, but still there is sufiicient surface or area to the float for the water pressure to act thereon and quickly and automatically close the valve except when it is held open by manual means, as presently described.

It will be seen that by removing the cap 21 one can take hold of the bail 20 and lift all the mechanism of the valve out of the chamber 16 so that it can be cleansed, repaired or renewed, and by this means the gasket 18 can also be reached and a new one inserted when necessary. It will further be observed that the valve is always held antomatically to place because the intake from the bore 15 is above the float 25, and thus the faucet is always positively closed.

The valve can be opened against the water pressure in any convenient way, but I prefer the mechanism shown, in which a finger 28 is arranged to swing upward from below the valve and lift it from its seat. The base of the finger turns in a recess 29 in the wall of the casing 10, and it fits a squared portion of Patented Aug. 24., 1909.

.As ,shown in the drawing it will 1beobserved that if the lever 31 is .pulled forward, the finger 28 is swung into the position shown by dotted lines in Fi 2,,and the ball valve '24 andfloat 25 are %ifted, while the liquid flows freely through the holes-27 and outthroughthe spout 14. If, howeventhe lever ,is released, the ;water. pressure on' the float 2-5v quickly closes the valve.

"-It will of course be understood that the "faucet can'be made in any ap roved design, and that any suitable *hand e mechanism can be used'forlifting-thevalve, without departing'fromthe principle of the invention. j-lt 'willxalso ;v be understood that the weight of-the handle31hasa'tendency to drop the fingerg28 and permit'the balllvalve 24 and zth'effloat 25- 50 drop sov as-toclose the valve even though there be no water pressure thereon.
